Understanding the replication link list
The replication Links page in the HCP System Management Console lists the currently defined replication links in which the current system participates. To display this page, in the top-level menu of the HCP System Management Console, select .
For each listed link, the replication Links page shows:
Name
The link name.
Type
The link type. The link type can be Active/Active, Outbound, or Inbound.
If the link is part of an erasure coding topology, the link type is followed by this icon:
Status
The link status, represented by an icon and text. The icon indicates the general health of the link. The text specifies the status of the link. The possible icons are:
The link is healthy. The statuses that can accompany this icon are:
Synchronizing data
On either system for an active/active link, the local system is sending data to the other system involved in the link.
Sending data
On the primary system for an active/passive link during replication, the primary system is sending data to the replica.
Receiving data
On the replica for an active/passive link during replication, the primary system is sending data to the replica.
The link is healthy, but normal replication is not occurring on the link. The statuses that can accompany this icon are:
Recovering data
On the replica for an active/passive link during the first part of data recovery, the replica is sending data to the primary system.
Completing recovery
On the replica for an active/passive link during final data recovery, the replica is sending data to the primary system.
Receiving data
On the primary system for an active/passive link during data recovery, the replica is sending data to the primary system.
Scheduled off period
No data is being sent on the link because the scheduled performance level for the current time period for the link is Off.
Suspended by user
On both systems for an active/active or active/passive link, activity on the link has been manually suspended. No replication or recovery is occurring.
The link is unhealthy. The statuses that can accompany this icon are:
Failed over
On both systems for an active/active or active/passive link, the link is currently failed over.
Remote storage full, link suspended
On the local system for an active/active link, on the primary system for an active/passive link during replication, or on the replica for an active/passive link during data recovery, the other system involved in the link does not have enough free space in primary running storage to accept any more data transmissions. In any case, HCP has automatically suspended activity on the link.
Local storage full, link suspended
On the local system for an active/active link, on the replica for an active/passive link during replication, or on the primary system for an active/passive link during data recovery, the local system does not have enough free space in primary running storage to accept any more data transmissions. In any case, HCP has automatically suspended activity on the link.
High error rate
On both systems for an active/active or active/passive link, errors are occurring at a high rate. If you see this status for:
- An active/active link, check the health of both systems involved in the link
- An active/passive link during replication, check the health of the replica.
- An active/passive link during data recovery, check the health of the primary system
In any case, also check the health of the network connection between the two systems involved in the link.
If you cannot find the problem, contact your authorized HCP service provider for help.
Stalled link
On both systems for an active/active or active/passive link, activity on the link has stopped. Check the network connection between the two systems. If the connection appears to be working properly, contact your authorized HCP service provider for help.
Unrecognized link
On either system for an active/active or active/passive link, the other system involved in the link doesn’t recognize the link. Restore the link. Then, if applicable, start data recovery.
Broken link
On both systems for an active/active or active/passive link, the Replication service cannot contact any nodes on the other system involved in the link. If you see this status for:
- An active/active link, check the health of both systems involved in the link
- An active/passive link during replication, check the health of the replica
- An active/passive link during data recovery, check the health of the primary system
In any case, also check the health of the network connection between the two systems involved in the link.
If you cannot find the problem, contact your authorized HCP service provider for help.
If more than one status applies to a link, the page shows the icon and text for only one of the statuses.
For additional information on the status of a link, hover over the status icon.
NoteThe System Management Console may not immediately reflect certain changes in link status.Alerts
If replication or recovery activity is paused for one or more tenants on the link, either of these icons:
Replication or recovery has been manually paused for one or more tenants on the link.
Replication or recovery has been automatically paused for one or more tenants on the link. To view text describing the condition that’s causing this alert, hover over the alert icon.
If replication or recovery is paused manually for one or more tenants and automatically for one or more other tenants, the page shows only the icon indicating an automatic pause.
The number of nodes on the other system that can receive replication transmissions from the current system. If the current system can determine the total number of storage nodes on the other system, the page shows that number as well.
